Nitric acid catalyzed hydrolysis of SO3 in the formation of sulfuric acid: A theoretical study

- We explore that the remarkably catalytic role in which nitric acid plays in the hydrolysis of SO3.
- We elucidate the reaction mechanisms of the SO3 with H2O in the presence of nitric acid.
- Of great importance is estimated for the formation of sulfuric acid with the assistance of nitric acid in the atmosphere.
